Abstract (en)

Provided are a light-receiving element which has sensitivity in the near-infrared region and in which a good crystal quality is easily obtained, a one-dimensional or two-dimensional array of the light-receiving elements is easily formed with a high accuracy, and a dark current can be reduced; a light-receiving element array; and methods for producing the same. A light-receiving element includes a group III-V compound semiconductor stacked structure including an absorption layer 3having a pn-junction 15 therein, wherein the absorption layer has a multiquantum well structure composed of group III-V compound semiconductors, the pn-junction 15 is formed by selectively diffusing an impurity element into the absorption layer, and the concentration of the impurity element in the absorption layer is 5 ×10 16 cm -3 or less.
